If you’re here, you’re probably concerned about your family’s health. Considering the state of world pollution, you are right to be concerned.

The amount of contribution you can make to world pollution is minuscule, at best. However, you have considerable power when it comes to indoor pollution. You can ensure your indoor atmosphere is clean and hygienic for your family.

And that’s precisely where air purifiers come in.

Air purifiers have recently become extremely popular because they can remove airborne particles and contaminants from your home. They consist of a fan and a series of filters that trap airborne pollutants such as dust mites, pollen, pet dander, and other particles, thereby improving the quality of air.

However, the amount and type of airborne particles they can purify depend on the type of filters used. Some air purifiers can only trap pollen, dust mites, and pet dander. Some advanced air purifiers can also trap gaseous emissions, smoke particles, and odor. And some too advanced air purifiers equipped with UV lights can even potentially kill germs, bacteria, viruses, and other microbes.

People suffering from allergies, asthma, or other breathing issues can benefit from air purifiers. Since air purifiers get rid of airborne particles, they remove most of your allergy and asthma inducers, such as dirt, dust, pollen, VOCs, smoke, etc. As such, while air purifiers can’t treat allergies or respiratory issues, they can help you breathe easier and avoid specific triggers.

However, an air purifier’s efficiency depends on the type of filters it uses, its CADR (Clean Air Delivery Rate), and other factors. The following are some factors to consider when looking for air purifiers for allergies and respiratory health:

  • Opt for an air purifier with a True HEPA Filter that can trap the smallest of dust mites and pollen.
  • The air purifier should include an Activated Carbon Filter that can trap gaseous emissions and smoke.
  • If you’re concerned about bacteria and microbes, you can also get an advanced air purifier with UV lights.
  • You should generally avoid air purifiers with an ionized filter because they release ozone gas, which can worsen respiratory issues and induce asthma attacks. If you do get an air purifier with an ionized filter, make sure you can turn it on or off.
  • Some people have asthma attacks induced by noise. As such, the air purifier should be extremely quiet.
  • The air purifier should have a high CADR rating because that determines how fast the device can purify the air in a room of a specific size. The CADR rating is usually calculated for pollen, smoke, and dust.
  • The air purifier should also have a high ACH (Air Changes per Hour) rating because that determines how many times the air within a room is circulated and changed in a single hour.

For the purpose of this article, we thoroughly examined and tested dozens of the best air purifiers on the market. We tested them according to their ability to filter various pollutants, their CADR rating, their noise level, efficiency, and various other verticals.

After narrowing down our options, we came down to the ten best air purifiers for allergies and family health. Furthermore, since CADR is one of the most important guarantors of efficiency, we’ve presented our selection in descending order of their CADR ratings.

Please continue reading for a detailed review of the ten best air purifiers for allergies and family health.

Important Note: Can an Air Purifier Stop Coronavirus?

In light of the recent novel Coronavirus outbreak, which has been declared a global pandemic, people have been asking, “will air purifiers prevent coronavirus?”

The short answer is likely NO.

There is no scientific evidence to suggest that air purifiers kill the coronavirus, despite a slew of misguiding promotional campaigns from some purifier companies.

True HEPA filters can remove air particles as small as 0.3 microns, but virus particles are often less than 0.1 microns in size. Furthermore, UV-C lights can theoretically kill some forms of bacteria and microbes through continued exposure — but there’s no evidence to suggest that they’re effective against coronavirus.

Please follow official guidelines to protect yourself and those around you from coronavirus.

Okay, now back to the review!

Pros

Cons

True HEPA Filter.

No timers, smart functions, or filter indicators.

18 pounds of Activated Carbon Filter made of natural materials.

Filter replacement is expensive.

Recyclable all-steel housing.

Can only replace the air twice in an hour, making it less than ideal for those who have asthma.

Suitable for large rooms.

Extremely powerful airflow.

Silent in the lowest setting.

Airpura R600 Design

Airpura R600 looks just like all other Airpura devices, i.e., it’s a large black cylinder with all-steel housing. The steel housing ensures there’s no off-gassing of fumes or vapors at any point in the product’s lifecycle. This Airpura air purifier is 93% recyclable.

This air purifier also includes a pressure seal on the filter housing. This maximizes the 99.97% HEPA filtration promise, ensuring all polluted air passes through the filters without any leakage. Furthermore, the filter chamber also includes felt gaskets for further sealing.

Airpura R600 has dimensions of 23” x 15” x 15”, and it weighs 45 pounds. This air purifier is designed with a 360° distribution airflow, which helps ensure maximum air circulation in every corner of the room.

Airpura R600 Filtration

Airpura R600 uses a 3-stage filtration system:

  • Pre-Filter: Airpura R600 uses a poly pre-filter that protects the primary filters by trapping large pollutants like pet hair and human hair. The pre-filter should be vacuumed clean or changed every six months. The standard pre-filter costs $39.98, and the cotton pre-filter costs $54.98.
  • Activated Carbon Filter: This air purifier uses an 18-pounds activated carbon filter made of coconut shell charcoal. Since it’s made of natural materials, there’s no risk of chemical leaks. One of the best carbon filters on the market, it can remove most of the smoke, odors, and gaseous emissions from your home, while maintaining a lifespan of 2 years. The cost of a new carbon filter is $219.98.
  • True HEPA Filter: This purifier uses a 40 sq. ft. True HEPA filter that can remove up to 99.97% of all contaminants that are as small as 0.3 microns. You can also upgrade the HEPA filter to a HEPA 14 filter for greater efficiency. You need to replace the true HEPA filter once every 3 to 5 years. The cost of a new HEPA filter is $179.98.

Airpura R600 CADR & ACH

  • Room Coverage: Airpura R600 has optimal room coverage of 2000 square feet, even though the Airpura website claims it is 2500 square feet.
  • ACH: Airpura R600 can replace and exchange the air in a 2000 square feet room within 30 minutes. As such, it has an ACH rating of 2x.
  • CADR: Airpura R600 can purify air at the rate of 560 cfm in general.

Airpura R600 Features

Airpura R600 is an extremely basic (yet powerful) air purifier, i.e., it serves the primary function of purifying air using filters, but it doesn’t do anything else. There are no filter replacement indicators, timers, or any smart features.

Airpura R600 Noise Level

At its lowest setting, Airpura R600 produces only 28.1 decibels of sound, which is about as loud as a whisper. At its highest setting, it produces 62.3 decibels of sound, which isn’t loud by any means, but you can hear it constantly.

Airpura R600 Energy Usage

In the lowest fan speed, Airpura R600 consumes 40 watts of energy. In the highest fan speed, it consumes 120 watts of energy. As such, the cost of running an Airpura R600 for 8 hours a day will be between $15 to $43 per year.

FAQs about Airpura R600

Is Airpura R600 good for a smoke?

Airpura R600 is better than most air purifiers when it comes to removing cigarette smoke because it has a large activated carbon filter and a specialized pre-filter that will capture the tar and prevent clogging. If there’s a smoker in your household, you should ideally get brackets to mount the air purifier on the ceiling to maximum efficiency.

How often should the filter be replaced?

  • Airpura R600 has three different filters with varying lifespans:
  • The pre-filter should be replaced every six months.
  • The activated carbon filter should be replaced every 18 to 24 months.
  • The true HEPA filter should be replaced every 3 to 5 years.

Austin Air HealthMate Design

Austin Air HealthMate is a large air purifier with steel housing and a powder-coat paint finish. Its available in four colors — Black, Midnight Blue, White, and Sandstone; it has dimensions of 14.5 x 14.5 x 23 inches, and it weighs 47 pounds.

This Austin Air HealthMate air purifier has CSA (Canadian Standards Association) approval, which means its completely safe. The filter chamber comes with secure felt gaskets that prevent leaks and maximize efficiency. It also features a 360° air intake with a perforated grill that ensures it absorbs air from all around your house and replaces it uniformly.

Austin Air HealthMate Filtration

Austin Air HealthMate uses a 4-stage filtration system:

  • Pre-Filter: The pre-filter protects the internal filters and captures the largest particles, such as large dust mites, pet hair, and fur.
  • Medium Particle Pre-Filter: Once the air has passed through the first pre-filter, it passes through the second pre-filter, which captures mid-sized particles. The presence of two pre-filters ensures that only the tiniest particles pass through and reach the HEPA filter. This considerably increases your HEPA filter’s lifespan.
  • Activated Carbon Filter: The 15-pound activated carbon filter also contains potassium iodide and zeolite, which helps it remove smoke, VOCs, odors, and toxic chemicals. The addition of potassium iodide enables this carbon filter to bind chemicals faster, increasing its effectiveness against chemicals and gaseous emissions.
  • True HEPA Filter: This air purifier features a 60 square feet Medical-grade true HEPA filter that removes 99.97% of all airborne particles that are as small as 0.3 microns. As an extremely large true HEPA filter, it can also capture some pollutants as small as 0.1 microns. While the HEPA filter is highly-effective, it’s also insanely expensive, costing $359. But since this filter can last five years, the cost is absorbed by the additional years of use.

Austin Air HealthMate CADR & ACH

  • Room Coverage: Austin Air HealthMate covers extremely large spaces of approximately 1500 square feet.
  • ACH: This air purifier can change the air in a 1500 square feet room every 15 minutes to 30 minutes. As such, it has an ACH rating of 2x to 4x.
  • CADR: With a strong CADR rating of 400 cfm, this air purifier can clean your room faster than most, making it suitable for family health.

Austin Air HealthMate Features

Austin Air HealthMate doesn’t offer any unnecessary features, opting instead for effectiveness and simplicity. You won’t find any timers, filter replacement indicators, or other smart features.

Austin Air HealthMate Noise Level

Noise level is perhaps Austin Air HealthMate’s Achilles heel. This air purifier uses a Permanent-Split Capacitor (PSC) motor attached over shock absorbers, which leads to an extremely loud fan. If you use Austin Air HealthMate in your home, you need to be prepared for constant white noise even in the lowest fan speed.

Even at its lowest setting, Austin Air HealthMate produces 50 decibels of sound, which is louder than the highest fan speeds in many purifiers. At its highest setting, it produces 66 decibels of sound, which is about as loud as a lawnmower.

Austin Air HealthMate Energy Usage

The noisy Permanent-Split Capacitor (PSC) motor is generally used to lower power consumption. However, in this case, the additional noise doesn’t help lower your electricity cost.

In the lowest fan speed, Austin Air HealthMate consumes 56 watts of energy. In the highest fan speed, it consumes 132 watts of energy. As such, the cost of running an Austin Air HealthMate for 8 hours a day will be between $20 to $48 per year.

Pros

Cons

Excellent performance.

No additional features like timers or filter indicators.

The presence of double pre-filters greatly increases the HEPA filter’s lifespan.

Extremely loud, even in the lowest setting.

Powerful CADR and ACH.

Operational cost is higher than the average.

Suitable for large rooms.

The cost of replacing the true HEPA filter is extremely high.

The carbon filter can remove several toxic chemicals thanks to the potassium iodide.

FAQ: Austin Air HealthMate

Is this air purifier effective in reducing cigarette smoke and tar?

Austin Air HealthMate is highly effective in reducing and removing cigarette smoke and tar from the atmosphere. However, if new smoke constantly blows into the room, it may be hard to remove the odor of smoke completely. While this air purifier can get rid of most of the chemicals in cigarette smoke, it won’t remove the odor clinging to the walls and furniture.

Does this air purifier remove sulfur dioxide, aka SO2, from the air?

Austin Air HealthMate does a pretty great job of removing SO2 from the atmosphere.

Is Austin Air HealthMate Energy Star rated?

Austin Air isn’t a member of AHAM (Association of Home Appliance Manufacturers), which is why it doesn’t have an Energy Star Rating. Instead, the tests are performed by Battelle Laboratories, which is an extremely reputable testing laboratory.

Sharp FPA80UW

Specifications 

  • Dimensions: 9.6 x 24.4 x 15.9 inches
  • Filters: True HEPA Filter, Activated Carbon Filter, Plasmacluster Technology (Ionizer)
  • Room Coverage: 454 square feet
  • ACH: 4x
  • CADR: 360 cfm
  • Noise Level: 23 - 55 dB
  • Energy Usage: 5 watts - 94 watts

Top reviews on Google

Sharp FPA80UW Design

Sharp FPA80UW certainly won’t be winning any points for aesthetics. This air purifier measures 9.6 x 24.4 x 15.9 inches, and it weighs 17.6 pounds. It’s a fairly chunky device — while it doesn’t draw attention to itself when kept in some corner, it can look pretty hideous if it’s visible.

The plate on this purifier stands a little apart from the air intake grill. There’s no base, which means it stands firmly on the ground. Like most air purifiers, it has a bottom-to-top purification system. However, in this case, the purified air is dispelled from the top, rather than from around the body. The controls for the air purifier stand on the front face of the device, making it difficult to change the settings.

All things considered, Sharp FPA80UW has an extremely corporate and functional appearance. While it may work great in an office setting, it won’t make for a pretty sight in your home.

Sharp FPA80UW Filtration

Sharp FPA80UW uses a 4-stage filtration system:

  • Pre-Filter: This Sharp air purifier has a large washable pre-filter that traps large airborne particles like pet hair. You don’t need to replace the pre-filter because you can simply wash it clean.
  • Activated Carbon Filter: This air purifier has a fairly standard activated carbon filter that removes odors, smoke, and some household chemicals. However, the carbon filter has a lifespan of only six months, which can lead to high replacement costs.
  • True HEPA Filter: The true HEPA filter can remove airborne particles with 99.97% efficiency and as small as 0.3 microns, getting rid of mold spores, smoke, germs, pet dander, dust, and so much more. It has a lifespan of only two years, which is considerably lower than many other purifiers. The cost of replacing a true HEPA filter is only $50.
  • Plasmacluster Technology: This is one of the most advanced forms of ionizer filters, capable of reducing stubborn pollutants from the air. The plasmacluster technology releases negative and positive ions, giving a positive charge to water molecules and a negative charge to oxygen. These ions bond to the surface of airborne microbes and organisms, which can decompose them into OH radicals. The ionizer filter breaks down the microbes and bacteria into water, which is then released into the atmosphere.

Sharp FPA80UW CADR & ACH

  • Room Coverage: Sharp FPA80UW has a pretty strong fan, and it can effectively clean moderately-sized rooms of 454 square feet.
  • ACH: This air purifier can change the air in a 454 square feet room every 15 minutes. As such, it has an ACH rating of 4x.
  • CADR: Sharp FPA80UW has a strong CADR rating of 303 cfm for dust, 293 cfm for smoke, and 360 cfm for pollen. As you can see, it is most effective in removing pollen particles from the air, but it can also remove other types of pollutants.

Sharp FPA80UW Features

Sharp FPA80UW may look basic, but it has some of the most useful and creative features amongst air purifiers.

  • Smart Sensor: This feature accurately identifies the current air quality and modifies its behavior accordingly for maximum efficiency. As such, it automatically ensures optimal cleanliness, while also preserving energy and keeping your HEPA filter clean.
  • Plasmacluster: The plasma cluster function, denoted by the button with the grapes, can be turned on or off. If you have family members with allergies or asthma, you should generally keep this turned off because ionizer filters may release trace amounts of ozone gas, which can exacerbate respiratory issues.
  • Light Dimmer: You can also hold down the grapes button to activate the light dimmer, turning this air purifier into a night light for children.
  • Quick Clean: Have you recently returned to an unclean, dusty, and moldy home after a long vacation? The Quick Clean feature discharges the maximum airflow cycle possible, along with plasmacluster ions, to clean up your home as fast as possible, ensuring you don’t have to remain in an allergy-inducing environment for long.

Sharp FPA80UW Noise Level

Sharp FPA80UW promises ‘LibraryQuiet’ operation, and it definitely lives up to that promise.

At its lowest setting, Sharp FPA80UW produces only 23 decibels of sound, which is barely a whisper. At its highest setting, it produces only 55 decibels of sound, which is noticeable, but still a lot quieter than the highest setting of most purifiers.

Sharp FPA80UW Energy Usage

Sharp FPA80UW is an Energy Star rated product with AHAM verification. This air purifier is incredibly energy-efficient and maintains low operational costs. 

In the lowest fan speed, Sharp FPA80UW consumes only 5 watts of energy. In the highest fan speed, it consumes only 94 watts of energy. As such, the cost of running a Sharp FPA80UW for 8 hours a day will be between $0.20 to $35 per year, which is peanuts!

Pros

Cons

Strong air filtration system. It can remove most airborne particles.

The pre-filter isn’t very powerful and doesn’t protect the True HEPA filter very well.

It can replace and exchange air four times in an hour, making it perfect for people with asthma or allergies.

The True HEPA filter has a lifespan of only two years.

It offers a library-quiet operation.

The activated carbon filter has a lifespan of only six months.

Operational costs are extremely low.

Not easy on the eyes.

It has some cool additional features that increase efficiencies, such as Smart Sensor and Quick Clean.

It doesn’t feature a 360-degree air dispersion system.

Pre-filter needs to be washed, doesn’t need replacement.

FAQs Sharp FPA80UW

Most air filters pull air from the front. Is the air intake from the rear a drawback?

Air intake from the rear may be an issue if the air purifier is placed up against the wall. However, if you place the air purifier a few inches from the wall or other obstructions, the direction of air intake won’t make any difference.

Is the HEPA filter permanent?

No, you have to replace the HEPA filter every two years and the carbon filter every six months.

How effective is Sharp FPA80UW against cigar smoke?

Sharp FPA80UW has an activated carbon filter, plus a plasma cluster ionizer. Between the two of those, it can absorb and clean almost all of the smoke particles from the atmosphere. If you’re not sure of the exact setting to use, switch to the Smart Sensor option — it will respond to the current air quality and use the optimal settings to balance cleanliness and energy conservation.

Rank on the Internet

Coway Airmega 400S Design

Coway is one of the biggest air purifier companies in Korea, and Airmega 400S is one of their most advanced products. This air purifier has a fairly standard set of dimensions, measuring 14.8 x 22.9 x 14.8 inches and weighing 24.7 pounds.

However, it truly distinguishes itself in terms of aesthetic sensibilities. While it’s still quite bulky, it looks fairly stylish with a silver or black metallic body supported on four legs. Instead of hiding the air intake grill behind a plate or on the rear end, this air purifier flaunts it openly. The entire body is surrounded by air intake grills, which allows the device to pull air from every single direction, increasing its efficiency while also offering aesthetic benefits.

While it looks pretty great, by air purifier standards, you may come across a few minor functionality issues. While this device is quite bulky and heavy, it features an extremely small handgrip that’s just big enough for one hand. As such, moving this air purifier around can be difficult.

The top of the air purifier features the outlet air vent that releases fresh air into the atmosphere. You can find all of the controls on the top of the air purifier. However, the air quality indicator is present on the front face, along with the air intake grill.

All things considered, if you want a fairly attractive air purifier for your home, Coway Airmega 400S is a pretty good option. However, the aesthetic quality does sacrifice functionality a little bit, so you may struggle while moving it around.

Coway Airmega 400S Filtration

Coway Airmega 400S uses a 2-stage combined filtration system:

  • Pre-Filter: The fabric washable pre-filter captures all of the larger airborne particles like hair and large dust mites. You can wash the pre-filter when it gets dirty and hang-dry it before re-installing it.
  • Max2 Filter: In most air purifiers, you have two separate levels for the activated carbon filter and HEPA filter. However, in this case, the Max2 filter is a unique combination of the two. As such, this second stage of filtration captures up to 99.97% of all particles as small as 0.3 microns, and a large volume of smoke, odors, and gaseous emissions like NH3 and CH3CHO. However, while the Max2 filter is highly efficient, it’s also fairly expensive and doesn’t have a great lifespan. On average, the Max2 filter will only last one year, and the cost of replacement ranges from $99 to $129. As such, the upkeep cost of Coway Airmega 400S is pretty high.

Coway Airmega 400S CADR & ACH

  • Room Coverage: The official room coverage for Coway Airmega 400S is 1560 square feet, which is pretty significant. It essentially means you can clean the air in a large room or a small house. However, there’s a caveat — it covers 1560 square feet at one ACH. If you need the air changed more often — as is necessary if you have allergies or asthma — you’ll have to use it in a far smaller room.
  • ACH: This air purifier can change the air in an 1560 square feet room every 60 minutes. However, if you use this in a 390 to 780 square feet room, it can offer an ACH rating of 2x to 4x. As such, depending on the room size, Coway Airmega 400S offers an ACH of 1x to 4x.
  • CADR: Coway hasn’t officially declared the CADR for Airmega 400S. However, on-ground tests suggest that it has a CADR rating of 340 cfm for dust, 350 cfm for smoke, and 400 cfm for pollen. While those statistics are quite decent for a small room of less than 400 square feet, they’re inadequate for an 1560 square feet room. As such, even though this air purifier is officially said to have room coverage of 1560 square feet, it’s actually ideal for rooms less than 780 square feet.

Coway Airmega 400S Features

Coway Airmega 400S offers a wide range of interesting features in addition to the essentials.

  • Smart Sensor: Coway Airmega 400S has one of the most accurate sensors amongst all the air purifiers. It can accurately detect the air quality and use features and functions that are most suitable to deal with it. This feature offers the optimal balance between energy consumption and purification.
  • Eco Mode: This mode helps lower the power consumption as much as possible while still keeping the air clean. However, using this mode isn’t recommended if you or your family members have asthma or other respiratory issues.
  • Smart Features: You can connect this air purifier to the Coway IOCare Mobile app to access a wide range of smart features. You receive important notifications, you can set schedules, and you can access filter monitoring. While the app is often riddled with glitches, this air purifier is still highly advanced without the app’s functionalities. 

Coway Airmega 400S Noise Level

Coway Airmega 400S is certainly one of the quietest air purifiers on the market.

At its lowest setting, Coway Airmega 400S produces 22 decibels of sound, which is about as quiet as the rustling of leaves. At its highest setting, it produces only 43.2 decibels of sound, which merely offers gentle white noise.

Coway Airmega 400S Energy Usage

Coway Airmega 400S is one of the most energy-efficient air purifiers available. It has an Energy Star certification, which guarantees energy-efficiency. Furthermore, the Eco Mode ensures you keep the cost down as much as possible.

FAQs Coway Airmega 400S

Does the sq. ft. area coverage needs to be a single open space or can it be multiple rooms with doors open?

In order for any air purifier to work efficiently, you need at least 2x to 4x air changes per hour (ACH). Even though the Coway Airmega 400S promotes itself as suitable for an 1560 sq. ft. room, it’s actually only suitable for spaces smaller than 780 sq. ft., if you want real efficiency. We advise against using it to purify such a large space.

Having said that, you further lose efficiency if you use it to purify multiple rooms, even with the doors open. Air purifiers should only be used for individual rooms unless you have an industrial air purifier in your HVAC system.

How loud is the filter at regular volumes?

As mentioned previously, this air purifier produces noise levels ranging from 22 to 52 dB. If you use this air purifier in fan speeds 1 or 2, you barely hear anything at all — it’s whisper-quiet. If you use this air purifier at full speed, the indicator light will turn reddish, and you’ll hear a gentle whirring sound, but it’s not at all loud enough to be distracting.

Honeywell HPA300 Design

Honeywell HPA300 is a sleek black air purifier that features a metallic body with rounded edges for safety and all-round full-body air intake grills.

Even though this air purifier is relatively small — measuring 9.2 x 20 x 22.2 inches — it’s designed intelligently to accommodate a large fan. Furthermore, since it’s surrounded by full-body air intake grills, it’s also extremely efficient. The function buttons are located on top of the purifier’s body, along with the air outlet grille.

The air purifier weighs 21 pounds, which is quite heavy and difficult to move around individually. However, the presence of two handles on either side of the device means two people can lift it and carry it with ease.

Honeywell HPA300 Filtration

Honeywell HPA300 uses a 2-stage filtration system:

  • Pre-Filter: Most pre-filters are made of a fabric that absorbs all of the large airborne particles like hair and dust mites. However, Honeywell HPA300 features an advanced pre-filter that includes the activated carbon filter. As such, not only can it absorb large air particles, but it can also absorb gases, odors, and several toxic chemicals. The presence of a pre-filter with activated carbon ensures greater protection from the HEPA filter, but it also means you need to replace the pre-filter every three months instead of simply washing it.
  • True HEPA Filter: The true HEPA filter is highly effective, removing up to 99.97% of all air particles as small as 0.3 microns. While this air filter is extremely effective, it only lasts for one year, and the cost of replacement is $68.

Honeywell HPA300 CADR & ACH

  • Room Coverage: Honeywell HPA300 has a truly formidable room coverage. Its official room coverage is listed as 465 square feet, which is large enough for most moderate-sized rooms. This room coverage may seem low compared to that of the aforementioned Coway’s coverage of 1560 square feet. However, that’s because Honeywell has listed the room coverage in accordance with maximum efficiency.
  • ACH: This air purifier can change the air in a 465 square feet room every 12 minutes. As such, it has an ACH rating of 5x, which is perfect for people suffering from allergies, asthma, or other respiratory issues. In fact, you can use this air purifier in a room larger than 1000 square feet, and still have it be fairly effective.
  • CADR: Honeywell HPA300 has an extremely strong CADR rating of 320 cfm for dust, 300 cfm for smoke, and 300 cfm for pollen. Such a rating is great for a room of 465 square feet.

Honeywell HPA300 Features

Honeywell HPA300 is largely a performance-centric air purifier and doesn’t place much value on flashy features. However, you do get a few basic features:

  • Timer: You can set timers for 2 hours, 4 hours, or 8 hours.
  • Turbo: You can use the Turbo mode when your home is extremely dusty and dirty, and you need to clear it immediately to avoid allergies.
  • Filter Indicator: You get filter replacement reminders when it’s time to change the filters.

Honeywell HPA300 Noise Level

As mentioned previously, Honeywell HPA300 has one of the most powerful fans with an extremely strong ACH and CADR rating. However, such power also comes at a certain cost — and that’s the noise level.

At its lowest setting, Honeywell HPA300 produces 39.3 decibels of sound, which is the sound of a bird call. It’s not the loudest sound, but it’s not as silent as many other purifiers in their lowest setting. At its highest setting, it produces 61 decibels of sound, which is the sound of several conversations in a restaurant or background music.

Honeywell HPA300 Energy Usage

Honeywell HPA300 certainly doesn’t have the highest consumption or operational costs out there. But it’s still not very energy-efficient.

In the lowest fan speed, Honeywell HPA300 consumes 40 watts of energy. In the highest fan speed, it consumes 130 watts of energy. As such, the cost of running Honeywell HPA300 for 8 hours a day will be between $15 to $50 per year.

Pros

Cons

Sleek and attractive design.

Pre-filter needs to be changed every three months.

All-round full-body air intake grills.

True HEPA filter needs to be changed once a year at the cost of $68.

Extremely effective true HEPA filter.

Awesome room coverage with 5x ACH and great efficiency.

It has some basic features like turbo, timers, and filter replacement reminders.

It can be loud and distracting.

Relatively high operational costs.

FAQs Honeywell HPA300

How often do the filters need to be changed?

The HEPA filters need to be changed every 12 months, and the pre-filter needs to be changed every three months. While this is the average lifespan, you may even have to change them earlier, depending on the amount of particulate contamination in your atmosphere.

Does this air purifier increase the temperature of a room?

No, Honeywell HPA300 doesn’t increase the temperature of a room. The air passing through the air purifier will facilitate air circulation after moving through the fan, without affecting the room temperature.

Can I clean the pre-filter every three months instead of replacing it?

Since the pre-filter comes with integrated activated carbon, cleaning it manually isn’t enough. You must replace the pre-filter every three months.

6. Blueair Classic 480i

Cost: $689.01 on Amazon

Blueair Classic 480i air purifier

Specifications

  • Dimensions: 15.5 x 25 x 28.4 inches
  • Filters: Particle Filter/ True HEPA Filter, Activated Carbon Filter
  • Room Coverage: 434 square feet
  • ACH: 5x
  • CADR: 300 cfm
  • Noise Level: 32 - 52 dB
  • Energy Usage: 15 watts - 90 watts

Rank on the Internet

Blueair Classic 480i Design

Blueair Classic 480i has a unique design compared to other air purifiers.

It features air intake and air release grills on two sides — side and top. Most air purifiers feature air intake grills on the body — as the air passes through the filters, it then comes out from the top.

However, in this case, the air input and output grills and placed side-to-side. As such, air goes in and comes out from the same direction. This design helps optimize airflow and increases efficiency.

The top of this air purifier features a digital control panel with LED icons for various functions such as the WiFi connection, filter indicator, speed, etc.

Blueair Classic 480i measures 15.5 x 25 x 28.4 inches, and it weighs 42 pounds, which makes it about twice as bulky as most other air purifiers. As such, moving it around may pose a challenge.

Blueair Classic 480i Filtration

Blueair Classic 480i doesn’t have the same filtration system as most other air purifiers. Other air purifiers have a fixed number of air filters — but, in this case, you can choose the type of air filter you want.

You have to choose either the Particle Filter OR the SmokeStop Filter. The following is an explanation of the two types of filters:

  • Particle Filter: Blueair Classic 480i has a Blueair Particle Filter made of polypropylene and polyethylene fibers that can capture most airborne pollutants and particles. It’s also equipped with HEPASilent technology, which is a combination of mechanical and electrostatic filters. When air passes through the HEPASilent electrostatic filter, the particles get electrified and move towards the filter. Between the mechanical and electrostatic capacities, this is one of the most effective HEPA filters available. The biggest issue here is that there’s no pre-filter, so there’s no protection for the particle filter. As such, the filter has a measly lifespan of six months, and the cost of replacement is $75. As such, you’ll be spending $150 per year just for filter replacement.
  • SmokeStop Filter: The SmokeStop Filter is basically the same as the aforementioned Particle Filter, but it also comes with an added Activated Carbon Filter made of magnesium dioxide and copper oxide. The filter is 100% recyclable, anti-bacterial, natural, and it also removes VOCs and chemical fumes, in addition to everything that a HEPA filter removes. If someone in your household has asthma or respiratory issues, it’s worth paying extra for the SmokeStop Filter.

Blueair Classic 480i CADR & ACH

  • Room Coverage: Blueair Classic 480i has an official room coverage of 434 square feet, which is good enough for large or moderate-sized rooms. Furthermore, this air purifier offers brilliant efficiency for such rooms, making it ideal for allergies and family health.
  • ACH: This air purifier can change the air in a 434 square feet room every 12 minutes. As such, it has a brilliant ACH rating of 5x.
  • CADR: Blueair Classic 480i has a CADR rating of 300 cfm for dust, 280 cfm for smoke, and 300 cfm for pollen, making it similar to the CADR rating of the aforementioned Honeywell air purifier.

Blueair Classic 480i Features

Blueair Classic 480i is a smart air purifier, and, as such, it comes with a wide range of smart features:

  • Smart App: You can use the Blueair Friend App on iOS or Android to remotely control your air purifier.
  • Night Mode: You can trigger the Night Mode to lower the fan speed and turn the lights off, so it doesn’t interrupt your sleep.
  • Timer: You can set timers using the device or the smartphone app.
  • Filter Replacement Indicator: The filter indicator on the air purifier will inform you when it’s time to replace the filters.
  • Smart Sensor: Blueair Classic 480i detects the air quality and automatically adjusts the fan speed to offer optimal benefits.

Blueair Classic 480i Noise Level

Blueair Classic 480i has been designed to reduce the noise level as much as possible. It senses the air quality around you to optimize the fan speed. The Night Mode feature reduces the sound as much as possible for the least interruption. And the HEPASilent feature increases the filter’s efficiency while also reducing the fan’s sound.

At its lowest setting, Blueair Classic 480i produces 32 decibels of sound, which is lower than library noise levels. At its highest setting, it produces 52 decibels of sound, which is still pretty low compared to the high levels of other purifiers.

Blueair Classic 480i Energy Usage

Blueair Classic 480i comes with an inbuilt air sensor that automatically adjusts the fan speed to strike the perfect balance between health and power consumption. Furthermore, this device is also Energy Star rated for its energy-efficiency.

In the lowest fan speed, Blueair Classic 480i consumes 15 watts of energy. In the highest fan speed, it consumes 90 watts of energy. As such, the cost of running Blueair Classic 480i for 8 hours a day will be between $5 to $33 per year.

Pros

Cons

The design facilitates smooth airflow.

It’s extremely bulky and heavy, making transportation difficult.

Highly effective filtration system.

The lack of a pre-filter leads to a lower lifespan for the HEPA filter — it needs to be replaced every six months.

Brilliant space coverage with great efficiency.

The annual cost of upkeep is extremely high.

It can be controlled remotely using the smartphone app.

The cost is quite high compared to other air purifiers of a similar caliber.

Night Mode and Smart Sensors offer optimal automatic adjustments.

Energy efficiency.

FAQs Blueair Classic 480i

Which filter does Blueair Classic 480i come with?

You can choose the type of filter you want with your Blueair Classic 480i. You can either get the Particle Filter, or you can get the SmokeStop Filter at an additional cost. The SmokeStop Filter is similar to the Particle Filter in most ways, except that it also includes an activated carbon filter.

Can you turn the blue LED light off?

Yes, you can turn the blue LED light off either using the smartphone app or by triggering Night Mode.

Which filter is the best for removing VOCs?

If you want to remove smoke, chemical fumes, odor, or VOCs, you should get the SmokeStop Filter because it includes activated carbon filter.

IQAir GC MultiGas Design

IQAir GC MultiGas is a Swiss-made air purifier, and that really comes through in the intelligent design. It features a sleek stainless steel body with typical bottom-to-top air intake grills. One of the most innovative features here is the 3D Ultra Seal that ensures the filters are sealed 100% to prevent any leakage, which, in turn, enhances efficiency.

This air purifier has an air intake grill at the bottom. The polluted air moves upwards through the filters, and it’s finally expelled from the air outlet on top. In most cases, when an air intake grill touches the ground, it also absorbs a lot of the surface dirt, which decreases the product’s efficiency. However, in this case, the bottom of the air purifier has a curved design that ensures the air intake grill is a few inches from the ground, which prevents it from sucking in surface dirt. Additionally, this air purifier also comes with four casters to further increase the distance from the ground and increase efficiency.

The top of the air purifier features the air outlet with the 320-degree EvenFlow Diffuser technology, which ensures that filtered air leaves from every angle, ensuring even distribution of fresh air. The top also features a touchpad with an LCD display for easy controls.

IQAir GC MultiGas measures 16 x 15 x 28 inches and weighs 29 pounds. However, unlike many other air purifiers, it’s extremely easy to move around because it features a handle and four wheels for mobility.

IQAir GC MultiGas Filtration

IQAir GC MultiGas uses a 4-stage filtration system:

  • HyperHEPA Filter: IQAir GC MultiGas uses a HyperHEPA Filter that goes well beyond the capabilities of a True HEPA. In addition to capturing 99.97% of particles as small as 0.3 microns, it also captures 95% of all particles as small as 0.003 microns. As such, it’s extremely effective at removing tobacco smoke, soot, and even some viruses. However, such a powerful glass microfiber filter comes with a heavy price tag. You need to change this filter annually, and the cost of replacement is $199.
  • Cartridge-Based Activated Carbon Filter: The activated carbon filter is made of 12 pounds of ABS plastics. This is the first stage in the removal of smoke particles and VOCs from the air. During this phase, the activated carbon traps most of the smoke and gaseous emissions.
  • Cartridge-Based Chemisorption: This filtration stage passes air through a chemically active alumina pellet that uses an oxidation process to break down harmful chemicals like formaldehyde and smoke particles. As such, between these two cartridge-based filtration layers, IQAir GC MultiGas is incredibly powerful in removing smoke, making it one of the best air purifiers for homes with smokers. The two cartridge filters need to be replaced every two and a half years.
  • Post-Filter Sleeve: This refers to micro-charged filtration sleeves that wrap around all of the cartridges mentioned above. As such, when air passes through them, there’s no emission of additional particles from the filter medium. The post-filter sleeve needs to be replaced every two and a half years.

IQAir GC MultiGas CADR & ACH

  • Room Coverage: IQAir GC MultiGas has one of the largest space coverages amongst all air purifiers, while still maintaining efficiency. It has an official room coverage of 1125 square feet, along with a high ACH.
  • ACH: This air purifier can change the air in an 1125 square feet room every 12 minutes. As such, it has an ACH rating of 5x. As such, this air purifier can ostensibly also purify an entire home or large auditorium.
  • CADR: IQAir GC MultiGas has a decent CADR rating of 300 cfm across all the verticals — dust, smoke, and pollen. However, if you equip your air purifier with the 3D optimized New Edition Fan, which runs at 1325 m³/h at 2750 rpm, you can also achieve a CADR rating of 776 cfm.

IQAir GC MultiGas Features

IQAir GC MultiGas is an extremely expensive and advanced air purifier, which is why people usually expect a vast set of smart features as well. However, this air purifier is a little lacking in features, at least relative to its price.

The following are some of IQAir GC MultiGas’ features:

  • Remote Control: You get a remote control with which you can control this air purifier from a distance.
  • Smart Sensor: It can automatically adjust the fan speed and settings according to the prevailing air quality in your room.
  • Timer: You can set times for operational hours and weekdays. You can also set specific fan speeds at different times.
  • Filter Replacement Indicator: It comes with an LED indicator that lets you know the condition of the filter.

IQAir GC MultiGas Noise Level

In most cases, an air purifier’s noise level has a direct relation to its fan power and effectiveness, i.e., a high-powered fan would also cause more noise. However, IQAir GC MultiGas has aerodynamic fans with shock absorbers that reduce the noise level, which drastically reduces noise levels while offering brilliant performance.

IQAir GC MultiGas runs at six different fan speeds. At its lowest setting, IQAir GC MultiGas produces 25 decibels of sound, which is about as quiet as the rustling of leaves. At its highest setting, it produces 59 decibels of sound, which can register as light white noise.

IQAir GC MultiGas Energy Usage

IQAir GC MultiGas has extremely low power consumption at the lower end but a fairly high consumption at the higher end.

In the lowest fan speed, IQAir GC MultiGas consumes 20 watts of energy. In the highest fan speed, it consumes 135 watts of energy. The cost of running IQAir GC MultiGas for 8 hours a day will be between $7 to $48 per year.

Pros

Cons

Intelligent design that increases airflow and prevents leakage.

HyperHEPA filter needs to be changed annually.

Easy to move around because of the wheels.

The cost of a HyperHEPA filter is $199.

Double gas-phase cartridges are ideal for smoke removal.

Lacks smart features.

HyperHEPA filter is even more effective than a True HEPA filter.

It doesn’t have enough features to justify the cost.

Low power consumption in low fan settings.

High power consumption in high fan speeds.

Extremely quiet.

Extremely expensive.

Brilliant room coverage. It can effectively purify large homes or auditoriums.

FAQs IQAir GC MultiGas

Will IQAir GC MultiGas get rid of airborne molds and mycotoxins?

Yes, IQAir GC MultiGas will easily capture mold spores because they are usually 3-40 microns in size, and HyperHEPA easily captures that range. However, the air purifier can only remove the mold spores in the atmosphere; it can’t eliminate mold exposure. If you have mold, you must eliminate it at the source.

Can the IQAir GC MultiGas be camouflaged or covered without restricting the airflow?

You should never cover up your air purifiers because they need ample space to facilitate airflow. They should ideally be placed several inches from obstructions.

Do the filters come with the IQAir GC MultiGas unit?

Yes, IQAir GC MultiGas comes with all the necessary filters — HyperHEPA Filter, Activated Carbon Filter, Cartridge-Based Chemisorption, and Post-Filter Sleeves. However, you will have to purchase new filters at specific intervals after the first set is done.

LEVOIT LV-H133 Design

LEVOIT LV-H133 is undoubtedly one of the most aesthetically attractive and pleasing air purifiers on the market. Far from being something to hide away in a corner, it’s worthy of openly flaunting in your home. You can choose the black or silver versions of the air purifier, both of which feature a plastic body.

This air purifier has an air output grill at the top and an air intake grill on one side of the cylindrical body. This air purifier also has cylindrical filtration layers within the body, which facilitates 360-degree intake. However, its capacity to absorb air from every direction is limited since it only has an air intake grill on one side. It would have been a lot better to have intake grills dotted all around the body.

The top of the purifier features an LED display with a touch screen and several commands, which makes the purifier feel modern. This air purifier measures 23 x 12 x 12 inches, and it weighs 21 pounds.

LEVOIT LV-H133 Filtration

LEVOIT LV-H133 uses a 3-stage filtration system:

  • Pre-Filter: LEVOIT LV-H133 uses a vacuumable fine pre-filter that absorbs all the large air particles to protect the internal filters. Since this pre-filter can be vacuumed, it has a pretty long lifespan.
  • True HEPA Filter: This is the primary filtration layer, and it can remove up to 99.97% of all airborne particles as small as 0.3 microns, including dust, pet dander, and some microbes. The size of the HEPA filter is about thrice that of most other True HEPA filters, which also makes it more effective and expensive. This HEPA filter lasts approximately six months, and it costs $84, which leads to a very high annual cost of upkeep.
  • Activated Carbon Filter: This final filtration level will get rid of smoke, odors, and gaseous emissions.

LEVOIT LV-H133 CADR & ACH

  • Room Coverage: LEVOIT LV-H133 offers room coverage of 538 square feet, which can cover moderate-sized rooms.
  • ACH: This air purifier can change the air in a 538 square feet room every 15 minutes. As such, it has an ACH rating of 4x.
  • CADR: LEVOIT LV-H133 doesn’t have a very powerful fan, which is evidenced by its comparatively low CADR rating of 274 cfm for dust, 285 cfm for smoke, and 287 cfm for pollen.

LEVOIT LV-H133 Features

LEVOIT LV-H133 has some cool features that you can be excited about.

  • Smart Sensor: It automatically adjusts the fan size according to the air quality. This optimizes airflow, conserves energy, and increases the filter’s lifespan.
  • Timer: You can set specific amounts of time for which it should run.
  • Sleep: This mode will make the air purifier run quietly in the lowest fan speed, so you’re not interrupted.
  • Filter Replacement Indicator: The indicator will let you know when it’s time to change the filters.

LEVOIT LV-H133 Noise Level

LEVOIT LV-H133 doesn’t have a very powerful fan, but at least it’s also extremely quiet. At its lowest setting, LEVOIT LV-H133 produces only 25 decibels of sound, which is whisper-quiet. At its highest setting, it produces only 54 decibels of sound, which is still pretty quiet.

LEVOIT LV-H133 Energy Usage

LEVOIT LV-H133 doesn’t have a very powerful fan, which also translates to lower energy consumption. At the highest fan speed, it has a power consumption of 49 watts. As such, the cost of running LEVOIT LV-H133 for 8 hours a day will be approximately $18 per year.

RabbitAir MinusA2 air purifier

Top search reviews across Google

Specifications

  • Dimensions: 24 x 22.8 x 10 inches
  • Filters: Pre-Filter, Medium Filter, True HEPA Filter, Customized Filter, Activated Carbon Filter, Ion Generator
  • Room Coverage: 815 square feet
  • ACH: 2x - 4x
  • CADR: 200 cfm
  • Noise Level: 25.6 - 51.3 dB
  • Energy Usage: 7 watts - 61 watts

RabbitAir MinusA2 SPA-780A Design

RabbitAir MinusA2 SPA-780A is available in two colors — Black and White. Visually, it looks nothing like most other air purifiers on the market. It’s a large square-shaped purifier measuring 24 x 22.8 x 10 inches.

The construction is mostly metallic, and it features an LED screen at the center, along with function buttons on the right. You also get special editions featuring paintings by Van Gogh and other artists, which firmly establishes it as one of the most attractive air purifiers available. You can even flaunt it in the middle of the room without fear that it will be an eyesore. You can even mount it up on a wall because it’s also extremely slim, measuring 10 inches.

The entire front surface of the air purifier serves as an air intake grill, maximizing its ability to take polluted air, which is then expelled from the top. This air purifier only weighs 19.4 pounds, and it is mountable, which also means you can easily move it to other parts of the house. 

RabbitAir MinusA2 SPA-780A Filtration

RabbitAir MinusA2 uses a complex 6-stage filtration system:

  • Pre-Filter: This is a washable pre-filter that captures most of the larger particles to protect the internal filters.
  • Medium Filter: If some airborne particles like dust mites, pollen, and pet dander pass through the pre-filter, then this layer will capture them. This offers a second layer of protection, which further increases the durability of the HEPA filter.
  • Advanced BioGS HEPA Filter: This is a True HEPA Filter that captures 99.97% of all particles as small as 0.3 microns. The advanced BioGS component makes the filter a lot more effective than most other HEPA filters. Furthermore, the presence of the aforementioned pre-filters increases its durability, ensuring it lasts for two years with replacing. The cost of replacing the HEPA filter is $85, which isn’t all that high, considering you only have to replace it once every two years.
  • Customized Filter: A unique innovation, RabbitAir MinusA2 allows you to customize this filter layer by choosing specific filters like Germ Defense, Pet Allergy, Odor Remover, or Toxin Absorber. As such, depending on what your greatest concern is (whether it’s germs, odor, chemicals and toxins, or pet allergy), you have a filter designed specifically for it.
  • Activated Carbon Filter: This layer traps all of the odors, smoke particles, and VOCs.
  • Ion Generator: If some airborne particles get through all of the previous stages, then the Ion Generator will electrically charge them, so they get magnetized to the filter. This layer, however, may also release ozone gas, which is why you can turn it off.

RabbitAir MinusA2’s filtration system is perhaps the most complex and comprehensive of any other air purifier on the market. While most air purifiers use two to four filters, this air purifier uses six stages of filtration. Furthermore, one of those layers is customizable to address a specific need that you have, making it perfect for homes with allergies, pets, smokers, or family health concerns.

RabbitAir MinusA2 SPA-780A CADR & ACH

  • Room Coverage: RabbitAir MinusA2 SPA-780A offers an official room coverage of 815 square feet.

FAQs

Will RabbitAir MinusA2 remove cigarette odor?

Yes, RabbitAir MinusA2 is extremely effective against cigarette smoke and odors. The activated carbon filter and the ion generator are effective against gaseous emissions, odors, and smoke particles. Furthermore, you can also opt for the Odor Remover customized filter to ensure even greater efficiency.

Which customized filter should I use for year-long seasonal allergies?

RabbitAir MinusA2 has six layers of highly-effective filtration. As such, regardless of the type of customized filter you opt for, it will remove all gaseous emissions, VOCs, smoke particles, odors, dust mites, pet dander, and other forms of allergen.

However, as far as the customized layer is concerned, you should ideally go for the Toxin Absorber. It will trap and reduce VOCs, gasses, and chemical compounds. If you have allergies, you should avoid using the ion generator because that produces trace elements of ozone, which can exacerbate your symptoms.

Germ Guardian AC4300BPTCA Design

Germ Guardian AC4300BPTCA is one of the shortest air purifiers on the market, measuring only 8.9 x 5.4 x 22 inches. If you place it on the floor, you’ll have to bend over to use its functions. However, the small size also lends itself to a low weight of only 9.45 pounds. As such, you can also place this air purifier on a tabletop.

This air purifier has an air intake grill at the back, and the air output is on top. As such, you should avoid placing this air purifier against the wall, leaving at least a few inches of distance from other obstructions. The control panel for this purifier is on top — it includes two buttons and an LED filter replacement light.

Germ Guardian AC4300BPTCA Filtration

Germ Guardian AC4300BPTCA uses a 3-stage filtration system:

  • Pre-Filter: The pre-filter includes activated carbon, which means it captures large airborne particles, along with gaseous emissions, VOCs, and odors.
  • True HEPA Filter: This filtration layer captures 99.97% of all air particles as small as 0.3 microns. Despite the presence of a pre-filter, this HEPA filter needs to be replaced every six to eight months.
  • UV-C Light: The final stage in the filtration process is the UV bulb, which immediately destroys the microbes, bacteria, and some viruses at a cellular level. As such, this layer is especially useful for those who have allergies or asthma.
